The Dawn Framing Camera Calibration Pipeline description document. This       
document describes the pipeline for calibration of the images acquired by     
both models of the DAWN Framing Camera (FC1 and FC2). It details its          
operation and implementation. The pipeline builds on the results of the       
analysis of in-flight and laboratory measurements. [adapted from Schroeder &

The Dawn Science Plan document. This document provides a description of the   
planned Dawn observations throughout the mission from launch through Vesta.   
It is provided as a source of information on the intent of the observations   
made by the instrument teams at Vesta. Note that not all of the planned       
observations actually occurred due to a variety of instrument resets and      
spacecraft safings.

The Dawn Framing Camera Software Inferface Specification (SIS). This document 
describes the contents and types of archive volumes belonging to all of the   
FC1 and FC2 NASA level 1 (CODMAC levels 2 and 3) data sets. This includes     
detailed descriptions of the data formats to allow users to read the data     
products.
